The factors which affect the average molecular weight of the polymer of AM and DMDAAC were investigated. The optimal reaction conditions are as follows: the concentration of monomer AM was 30%, while DMDAAC was 5%; the reaction temperature was 30℃, the amount of initiators at the low temperature stage was 0.05‰(compared to the weight of the monomers joining the polymerization), while V-50 was 0.025‰, the weight ratio of potassium persulphate to sodium bisulphite is 1:1, the amount of carbamide was 40‰, and complexing agent was 0.05‰, besides, aerate nitrogen gas for 8min, then the high molecular weight polymer (M=1.217×10^7) could be got after 16h reaction.

研究了影响AM与DMDAAC共聚物的平均分子量的因素，得到了优化条件为：单体浓度为30%，DMDAAC与AM摩尔比为5：95，聚合温度为30℃，低温段引发剂用量为0.05‰，K2S2O8与NaHSO3质量比为1：1，偶氮二异丁基脒盐酸盐(V-50)用量为0.025‰，尿素用量为40‰，乙二胺四乙酸二钠(EDTA-2Na)用量为0.05‰，在此优化条件下聚合反应16h后得到分子量为1.217×10^7的阳离子型聚丙烯酰胺。

The diluent contain magnesium chloride, potassium citrate, sodium glutamate, dipotassium hydrogen phosphate, monopotassium phosphate and fructose, semen vitality is hightest after frozen.The average value is 0.52,highter than other 5 diluent significantly (P﹤0.01).So chose this diluent as semen cryopreservation diluent on chicken. Definite cryoprotectant, equilibrium time and thaw temperature:On the base of test one,research freeze sheltering effect about glycerin, DMSO ,DMA and DMF, each with 4 consistency.The result showed that 10%DMSO sheltering effect is the best, the next is 4%DMA,semen vitality are 0.58 and 0.55 after frozen.
